NFL players weren't messing around on this Throwback Thursday.
As part of the league's #LetsPlayFootball initiative, players dug through family photo albums and old varsity yearbooks en masse.
The end result? Perhaps the greatest treasure trove of #TBT photos you'll ever see — all to gear up for another season of high school football.
You can learn more about the #LetsPlayFootball campaign right here. Just make sure you come back for these amazing old school pics.
